BUTTON.

SPECIFICATION forming part of Letters Patent No. 394,132, dated December4, 1888.

Application filed September 12, 1888. Serial No. 285,224. (No model ToaZZ whom, it may concern.-

Be it known that I, (HARLES PRENTICE, of Putnan'nin the county ofWindham and State of (onnectim1t, have invented certain n cw and usefulImprovements in Buttons; and I do hereby declare the tollo wing to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in buttons, and more particularlyto buttons intended to fasten carriage-curtains, detachable portions ofleather harness, and button shoes.

The object isto provide a button over which the lnitton-hole may bereadily passed without unduly stretching it, and which may be thenadjusted to lock the part in which the button-hole is formed thereon andbe automatically held in locked adjustment.

A further object is to provide a button which shall. be simple, durable,and quite inexpensive.

\Vith these ends in view my invention consists in certain features ofconstruction and combinations ot' parts, as will be hereinafterdescribed, and )ointed out in the claims.

In the accompanying drawings, Figure 1 represents a curtain locked to asupport by thebutton. Fig. Qrepresents the curtain partially adjustedover the button, showing the position of the button to receive thecurtain. Fig. 3 represents the button in side elevation, and Fig. 4-represents the several parts of the button in detail.

A represents a port ion of anysuitable frame or support to which it maybe desired to fasten a curtain strap or flap of any description; and forthe purpose of showing the use of the button a curtain, B, is hereinshown as the part to be secured to the frame or supturning head portionE preferably consists of a spring-wire loop, the ends of which areturned to form eyes c, which loosely embrace the reduced portion (I ofthe standard and permit the loop E to be swung at right angles to theaxis of the standard.

The branches of the spring-wire loop or head E have a tendency tosprcz'ul apart t'arther than the distance they occupy when in positionon the stamlard, and the stamlard is provided with shoulders 11 (I atthe extremities of the reduced portion (I, which serve to retain thebranches in their partially-closed adjustment, and hence producefriction between the eyes e oi the loop and the shoulders (1. (1", whichfriction serves to retain the loop in a position in which it may beturned.

\Vhere the standard or shank l) is to be secured to a t'rame, as shownin the drawings, I find it desirable to employ a screw to form thereduced portion d of the shank, and the enlarged portion l) is t'm'medby a cylindrical. cap or short tube, through which the screw (1 cxtcmlsinto the frame, 1 he port ion 1) being cramped between the lower orinner branch of the loops E and the frame, and the top of the portion Dand the head of the screw forming the shoulders d (7 This constructionhas the advantage of allowing the spriug-tension of the branches to beincreased or diminished by turning the screw (1 in or out, and henceregulating the readiness with which the loop may be turned. \Yhen thecurtain is to be fastened, the loop or head E is turned into position,(shown in Fig. 2,) so as to correspond to the direction of the slitportion c of the button-hole. The curtain is then pressed over thebutton, the standard or shank passing through the portion c of thebutton-hole and the loop E through the slit (1, and when in position theloop or head E is turned to the right or left and the curtain is lockedin position.

The spring-tension ot' the branches of the loop 1 serves to hold theloop in position until it is positively swung again into position toadmit of the removal ot'the curtain.

It will be observed that there will be little or no strain upon thebutton-hole, because of the very narrow portion of the button passingthrough the narrow portion of the button hole.

It will also be seen that the abovedescribed button might be employed tofasten a part which was essentially rigid about the buttonhole by simplymaking the button-hole large enough to admit the button when turned intothe position shown in Fig. 2.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention; hence I do not wish to limit myselfstrictly to the construction herein shown and described; but,

'Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The described button, consisting of a standard or shank portion and aswing springhead seated on the standard or shank portion, the saidspring-head being held in its swinging adjustment by its own tension,substantially as set forth.

2. The herein-described button, consisting of the standard or shank, andthe spring loop 1 and a base portion surrounding the screw,

and a swing spring-wire loop or head having its branches compressedbetween the head of the screw and the said base portion, substantiallyas set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing. witnesses.

CHARLES PRENTICE.
